Has the beef industry hit the tipping point when the unintended consequences of animal size outweigh the benefits? Industry leaders say rising carcass weights have boosted beef supply and efficiency, but they have also increased bruising, mobility issues, heat stress and economic risk.
Kevin Good, CattleFax vice president of market analysis, says carcass weights the last two years have gone up by 52 lb., with carcasses now averaging 975-990 lb.
“That’s an offset of 2 million head harvested,” he explains.
While the added weight has helped fill the supply gap due to the reduced cow herd and fewer cattle on feed, Jessica Lancaster, NCBA senior director of product quality and safety research, says these huge incremental shifts in carcass weight can certainly cause challenges.
Lancaster was a guest on “AgriTalk” Thursday, discussing carcass size research as well as foreign object research results.
Today’s Bigger Animals Are Testing Transport and Plant Limits
The Cattlemen’s College session “Bigger Cattle, Bigger Decisions: Managing Health and Welfare as Cattle Size Increases” featured industry experts Scott Pohlman, Cargill director of beef supply chain sustainability; Lily Edwards-Calloway, Colorado State University associate professor of animal science; and AJ Tarpoff, Kansas State University Extension veterinarian.
From longer days on feed to tougher transport and processing, the panelists discussed how a more efficient, heavier animal can strain welfare, infrastructure and profitability. They all agree proactive management and research are critical to dealing with the rising carcass weights.
Here are some key takeaways from their conversation:
1. Structural Shift: Fewer Cows, Bigger Cattle
Pohlman says the U.S. cow herd is at its lowest level since the Roosevelt administration.
Feedlots have compensated by adding days on feed and pushing carcass weights sharply higher — approaching 975-990 lb. — resulting in similar total beef supply with fewer animals but much larger individuals.
2. Efficiency Gains Are Real, and So Are the Risks
According to Tarpoff, the larger, heavier cattle and longer feeding periods have improved overall efficiency: more beef with fewer animals, less total feed and water per pound of beef. This has helped “backfill” lost production from the smaller cow herd.
However, longer time in the system means:
- Higher probability of adverse outcomes.
- Rising death loss and greater economic risk per head, because each animal is more valuable.
3. Welfare: Tipping Point Concerns Around Size
Welfare is framed around biological functioning: growth, health and reproduction, the ability to express normal behavior and the freedom from discomfort, fear and distress.
Edwards-Calloway says there is a particular concern for animals at the extremes of the size bell curve, whose welfare can be “pretty compromised.”
The industry must proactively address welfare challenges associated with larger cattle to maintain consumer trust. Edwards-Calloway says if consumers think the industry knew about a welfare problem and didn’t act, that’s seen as worse than making an honest mistake and fixing it.
4. Transport and Packing Plants: Systems Not Built for Today’s Cattle
Edwards-Calloway explains transporting from feedlot to packing plant is still one of the most stressful phases, even with best practices.
Research has often controlled for size rather than explicitly asking how large size affects outcomes. She says evidence suggests larger‑frame cattle have more traumatic events and bruising on certain trailer types.
Not all fed cattle are fit for transport; there’s a call for mobility scoring at loading, not just at the plant, she adds.
Pohlman says the frequency of bruising in the 2022 National Beef Quality Audit was the highest on record, with major/critical bruises increasing. He stresses the economic impact is significant at about $110 million from loin bruises alone.
He also says mobility scores at arrival have worsened.
Processing facilities built decades ago are struggling to accommodate today’s larger cattle. Plants are having to modify pen densities, single-file alleyways, restrainer sizes, intervention cabinets and even re-engineer rail systems to handle the increased weight and size of modern cattle carcasses.
5. Heat Stress, Dark Cutting and Seasonal Losses
Heat stress represents a more than $650 million annual loss to the industry, with heavy, near-slaughter cattle at highest risk. Larger animals have increased difficulty with thermoregulation, making heat-stress management increasingly critical as cattle weights continue to rise.
Tarpoff says summer heat correlates with higher dark‑cutting rates, causing additional carcass‑value loss.
6. Call to Action: Upgrade Infrastructure and Management for a ‘Different Animal’
Today’s cattle are heavier, bigger‑framed and take up more space per head than 10 to 20 years ago. Now is the time to reinvest in infrastructure: pens, water systems, shade and heat‑stress mitigation, transport equipment and plant modifications.
Tarpoff says the industry needs to be nimble enough to make individual outcome decisions because every animal is a bigger financial and reputational stake.
He encourages the industry to consider welfare investments — comfort, health, mobility and heat mitigation — as economic investments with real returns in performance and risk reduction.
Tarpoff stresses that now is the time to adapt systems to the realities of larger cattle so the industry can keep delivering high‑quality, efficient beef without eroding welfare or consumer trust.
